Keysight 34924A Reed Multiplexer, 70 CH, 2 or 4 Wire, 150V, .5A, 78-Pin Dsub, For 34980A Mainframe

70-Channel Reed Multiplexer for 34980A

• 70 2-wire channels
• Mixed 2- or 4-wire configurations
• High-speed reed relays, with relay counter
• 500 ch/s scanning
• +/-150V peak, 0.5A switch; 1.5A carry current

The Keysight 34924A module for the 34980A Multifunction Switch/Measure Unit is a high-density, high-speed multiplexer for general purpose scanning. It uses reed relays to achieve scan rates up to 500 channels-per-second. Use this module for high-throughput automated test applications as well as high-speed data logging and monitoring tasks.

2- and 4-wire channels may be mixed on the same module. Standard 78-pin Dsub connectors allow for use with standard cables, terminal blocks, or mass interconnect solutions.

346C/H06 includes APC 3.5 (m) connector with approx. 5 dB nominal ENR.

• Frequency range: 10 MHz to 26.5 GHz
• Nominal ENR 5 dB
• VSWR: < 1.35:1
• Connectors: BNC (f) input bias / 3.5 mm (m)
• Low SWR for reducing noise figure measurement uncertainty
• Individually calibrated ENR values at specific frequencies

Keysight 346C noise source is the ideal companion to Keysight’s noise figure solutions. Since it is broadband (10 MHz to 26.5 GHz), it eliminates the necessity for several sources at different frequency bands. The low SWR of the noise source reduces a major source of measurement uncertainty; reflections of test signals.
